Review This Product

By Christopher Of Idaho
Bought a 20" barrel from Craig, and after breaking in the barrel, it shoots 5 shot .250" groups at 100 yards and .465" groups at 200 yards. Using 50 grain V-max and 23 grains of reloder 7 and federal small rifle primers. Couldn't be more happy with this barrel!

UPDATE: No question about this is an outshanding barrel indeed. Just got back from the range doing a function test on a build projest and the rifle is already grouping well. Next step is to break in the barrel to insure there is no copper fouling. After that I will condition the barrel for about 15 rounds using Tetra Gun lubracant between each shot. By doing this you will obtain maximum accuracy with clean up being very easy. I'm not one to just set down at the bench and bang away with a can full of military ammo or cheap steal case rounds, I go for the gold and do my best to get supreme accuracy out my build projects. I feel sure this barrel will be able to acheive clover leaf if not better groups with the right load. I tend to lean towards the 55 grain Hornady V-Max with 25.2 grains of Benchmark. This load shoots extreamly well in three other rifles that I've built using the 16" barrels. With the 1 in 9 twist rate, you can drive heavier bullets as well just fine. All and all, I can't say enough good things about these barrels. Economical, Excellent quality and a great fit. Can't go wrong, I highly recommond using them and I'm sold on these barrels for futrue builds.

My brother and I bought a couple of these barrels because we wanted to build two very cheap rifles. We bought cheap free float handguards and used left over parts from other builds to complete the rifles. What we discovered was that the cheap guns with these barrels will out shoot the high end guns we had built. With cheap 62 gr. Privi ammo our first 5 shot group at 100 yds for each rifle was .5 in. This was accomplished by using bipods, not rifle rests. This is with a stock mil spec trigger. These barrels are the real deal. At first we thought it must be a fluke. But both rifles display a consistent matching leveI of accuracy. We were so impressed we bought a 16" heavy for another build. It also displays a very high level of accuracy. It shot a .75 inch group for the first 5 rounds. This was done by my 11 year old nepew on a windy day. I have since upgraded the trigger for Chepo. We are developing loads to get the most out of these guns. This is the most accrate rifle I have ever owned. You can't go wrong buying these barrels.

I bought one of these and am very glad I did wanted a 20" version to get a little more range.
